CHlCKEN-BROODER.

SPECIFICATION formingpart of Letters Patent No. 787,671, dated April 18, 1905.

Application filed April 21, 1904. Serial No. 204,232."

To all whom, it may concern:

Be it known that 1, JOHN N. JAOOBSON, a

citizen of the United States,residin at Mansfield Center, in the county of To land and State of Connecticut, have invented certain new and useful Improvements in Chicken- Brooders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,.and to the letters of reference marked thereon, which form a part of this specification.

This invention relates'to new and useful improvements in chicken-brooders; and the after fully described and then specifically de-' fined in the appended claims.

My invention is illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings similar letters of reference indicate like parts in the views, in which Figure 1 is avertical sectionalview through my improved brooder, showing parts in ele- I vation. Fig. 2 is a longitudinal sectional view through the brooder on line 2 2 of Fig. 1. Fig. 3 is a sectional view on line 3 3 of Fig. 1. Fig. 4 is a sectionalview transversely through the brooder, showing the partitions with a hinged door in elevation.

Reference now being had to the details of the drawings by letter, A designates the casing of the brooder, which may be of any size and shape, and B is a partition dividing the casing into two compartments, one of'which contains a heating-chamber C, which is fastened to the cover D, which is hinged to the casing, and said compartment containing the heating-chamber has double floors, (indicated in the sectional view by letters E and E) with a space intervening between the same, and on the inner face of the front wall of the casing is a flue or passage-way E communicating with a space between the two floorings, and inlet-apertures e afford means of communication between the compartment containin the heating-chamber and said flue. Suitable screens 6 are placed over said openings or .apertures to prevent chickens or foreign matter entering'said flue. One side of the casing has a double wall, said walls being indicated in the drawings by letters G and G and spaced apart, said space communicating with the space intermediate the double flooring and leading up to the upper edge of the casing, where the space is closed and provided with exit-apertures N,which are adapted to receive pipes K, passing through apertures in the cover, and which pipes when the cover is closed communicate with the spaceintermediate the double sidings. When said cover D is closed, a continuous passageway will be afiorded through the apertures N and K and pipes K and through which the vitiated air coming from the interior of the compartment may escape to the atmosphere.

Upon the front side of the brooder-casing is a boxing Q, in which a lamp Q of any suit.- able kind affording means of supplying heat is positioned, and a door Q is hinged to said boxing and provided with a Window 9, whereby access maybehad to the interior of the boxmg or sight of the same had through the window. A series of apertures O" are made through the lower end of the side of said boxing for the purpose of supplying fresh air to the interior of the casing for combustion purposes and for ventilating the interior of the brooder; A window "a is provided in the front Wall of the casing, and a thermometer A is positioned inside of the casing adjacent tothe window a, whereby the tem erature of the brooding-chamber may be from the outside.

The front wall of the casing has a recessed etermined ortion a, adapted to receive the contracted end C of the heating-chamber, and depending from said contracted end of the heatingchamber is a cylindrical passage-way G which when the cover D is closed is adapted to telescope over the end of a chimney of a lamp positioned in said boxing. Said heating-compartment has a transverse partition C dividing it into two compartments. The upper compartment (designated by letter O) is adapted to receive fresh air through the apertures O, which are positioned in the lower part of the boxing containing the lamp, and the fresh air passes through said space and makes exit at the point indicated by the arrow J near the upper end of the compartment and adjacent to the rear wall thereof, the course of the fresh air being indicated by i the arrows as it issues in the upper rear end the chickens are allowed to pass.

of the compartment and passes down near the bottom of the compartment and makes exit through the apertures e and continuing its course, as indicated by arrows, between the two floorings and the double siding preparatory to its making exit through the pipes which communicate with the space between the rear walls of the casing.

The heating-compartment C only is provided with series of transverse partitions, having their alternate ends free, whereby the heat which enters the heating-chamber from the lamp is caused to travel back and forth repeatedly until it finally escapes throughthe chimney R to the atmosphere.

Hinged upon the partition B is a door I, adapted to partially close the opening between the two compartments in the brooder, and fastened to the lower free edge of said door is a fabric I, by which the chickens are allowed to freely pass. This hinged door is provided for the purpose of allowing the smaller chickens to pass into the compartment containing the heating-chamber, and When it is desired to adapt the brooder for use with larger chickens said door may be swung open to allow the chickens to pass freely from the compartment containing the heating-chamber into the second chamber at will. Said second chamber is provided with a window upon one side and slide-covered apertures, whereby the contents of the compartment may be seen from the outside, and a sliding door T is provided, through which A cover S is hin ed to the compartment containing said sliding door, whereby ready access may be had to the contents of the brooder.

From the foregoing description, when taken in connection with the drawings which form a part of this application, it will be observed that an efficient means for thoroughly ventilating the brooder is provided, in which the fresh air is drawn into the heatingchamber and caused to circulate back and forth through the circuitous course in the heating-chamber, thereby utilizing the heat to its fullest extent before it escapes to the atmoshpere, and in the provision of means for drawin the fresh air through a compartment of the heating-chamber and making exit near the top of the brooding compartment and thence passing down through and making exit through the space between the double flooring and double siding, thus serving to keep the bottom and side of the compartment from cooling, and by the provision of the hinged door in the partition between the two compartments of the casing means is provided for the ready passage of the larger chickens by fastening the door open.

While I have shown a particular detailed construction .of chicken-brooders embodying the features of my invention, it will be understood that I may make alterations, if desired, in the detailed construction of the apparatus without in any way departing from the spirit of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A chicken-brooder comprising a casing having a double bottom and a double end, a

hinged cover to said casing, a fresh-air-heating chamber fastened to said cover, a compartment heating-chamber attached to and beneath said fresh-air-heating chamber, a brooding compartment underneath said chambers, a heater communicating with said compartment heating-chamber, said fresh air-heating chamber communicating with the interior of said casing, and the latter communicating with the atmosphere through a passage-way leading from the broodingcompartment through the double bottom and end of the casing, as set forth.
